Abstract

The invention provides an immobilized microorganism production device and production method. The production device includes a bracing frame, a material stirring barrel, at least two reaction tanks and a water tank. The material stirring barrel and the water tank are arranged at the upper part of a bracing frame, adjacent to each other. The two reaction tanks are arranged at the lower part of the bracing frame, adjacent to each other, and form mutual circulation. The water tank communicates with the material stirring barrel and the reaction tanks, respectively, for water supply and water replenishing. Material discharging pipes capable of being opened and closed are arranged at the bottom of the material stirring barrel and align right with the reaction tanks for dripping of materials. Through uniform stirring of material mixing and material particle forming, automatic control is achieved, the embedding technical process is further simplified, the high yield is increased, and stable operation and the product quality are ensured.

Description

technical field [0001] The invention belongs to the technical field of environmental protection machinery, and relates to an immobilized microorganism production equipment and a production method. Background technique [0002] At present, in order to deal with the increasingly serious pollution problem, scientists from all over the world are trying to find water treatment technologies with low cost, low energy consumption and low secondary pollution. [0003] Due to the unique role of microorganisms in the removal of pollutants, biodegradation is regarded as a relatively effective, economical and energy-saving water treatment technology. When the existing traditional microbial technology treats sewage, it usually directly inoculates microorganisms in the sewage to be treated, and reduces the concentration of pollutants through the growth, absorption and metabolism of microorganisms. [0004] However, due to environmental factors, competition, easy loss and other reasons, th...
